Chelsea Therapeutics Rockets Upward on Clinical Trial Data

So yesterday I was cautiously optimistic on Chelsea Therapeutics' 2nd go around with their Phase III Clinical Trial and I will eat crow on that story. I am simply a cautious investor. There is nothing wrong with that. I just want the facts before I jump into an investment.

But if the story had gone the other way, people would have lost a lot of money today upon negative results. I just wasn't so sure it would work this time around. I see now that it will be a good run-up candidate pending FDA approval. The stockcould go down a little after all the hoopla today and when it hits a bottoming price I see it as a buy. I'm not so sure I would be buying it just yet as there will be some selloff after today's news but putting a limit price target on the stock could be a good idea.

Most of the trading was done by Wall Street Investors in Pre-Market hours, so if you bought it this morning you might have lost a small chunk of change. Wall St. has a funny way of controling things before and after trading hits the floor for the everyday investor. They like to control the floor and let the little guy suffer sometimes. I won't go too much into that but you have to be careful when playing with the big boys in this game. Today is a good example if you look at todays stock chart.

(GLOBE NEWSWIRE) -- Chelsea Therapeutics International, Ltd[Wikinvest: (CHTP 5.74, +0.01, +0.18%)] announced that preliminary analyses of its Phase III NORTHERA(NYSE:TM) Study 301 met its primary endpoint. Treatment with Northera provided clinically meaningful and statistically significant improvement (p=0.003) in symptoms associated with neurogenic orthostatic hypotension (NOH), a chronic and often debilitating drop in blood pressure upon standing. Study results also showed that Northera was both safe and very well tolerated.

"We are extremely excited by these top-line results which provide validation of the safety and efficacy of Northera as a novel treatment for symptomatic neurogenic orthostatic hypotension, a serious condition for which there is an urgent need for improved treatments," said Dr. Simon Pedder, president and CEO of Chelsea Therapeutics. "Symptoms of chronic neurogenic orthostatic hypotension are severe, not only putting patients at high risk for falls and associated injuries but also severely impacting their quality of life and generating significant added health care costs. Northera is the first and only drug to repeatedly demonstrate clinical improvement in these patients by both alleviating symptoms of neurogenic orthostatic hypotension and improving their ability to perform daily activities."

Northera Trial Meets Primary and Multiple Secondary Endpoints

Patients randomized into this double-blind, placebo controlled study were evaluated for symptomatic and functional improvement using the orthostatic hypotension questionnaire (OHQ), which is specifically designed to rate the severity of symptoms resulting from low blood pressure and the degree those symptoms interfere with a patient's ability to perform activities of daily living.

The OHQ is a two-part questionnaire that uses an 11-point scale (zero to 10) to assess the severity of six symptoms on the orthostatic hypotension symptom assessment scale (OHSA) and four patient function criteria on the orthostatic hypotension daily activities scale (OHDAS). The trial's primary outcome measure, the composite OHQ score, reflects the average improvement (decrease) in mean OHSA and OHDAS scores.

Notably, in addition to the symptomatic and functional benefits registered on the OHQ, an analysis of blood pressure findings validate Northera's unique mechanism of action and confirmed the preferential effect of Northera on standing systolic blood pressure versus supine systolic blood pressure. Northera demonstrated a statistically significant improvement in standing systolic blood pressure (SBP) (p&lt; 0.001) relative to placebo with Northera patients reporting a mean increase of 11.2 mmHg compared to a mean change of 3.9 mmHg in standing SBP for the placebo group.This significant improvement was achieved with a relatively minor impact on supine blood pressure, with mean standing SBP for patients on Northera increasing 12% compared to only a 6% increase in mean supine SBP. Furthermore, no patients receiving Northera had SBP&gt;200 mmHg during the comparative phase of the trial.

No Significant Adverse Events

As anticipated, Northera proved to be safe and well tolerated at all dose levels. Headache (7.4%) was the most common adverse event reported, with all cases considered mild. Consistent with prior study results, treatment with Northera was associated with fewer patient reported falls. In Study 301, all 3 patient-reported falls were in the placebo arm while no patients on Northera arm reported falling during the one-week treatment period.

Innovative Study of Symptomatic Benefit Conducted Under Special Protocol Assessment

Study 301 was a randomized, placebo-controlled Phase III trial designed to measure the efficacy of Northera in treating symptoms of neurogenic orthostatic hypotension in patients suffering from primary autonomic failure.

The study was conducted under a Special Protocol Assessment (NYSE:SPA) granted by the FDA in February 2008. An SPA provides a binding agreement that the study design, including trial size, clinical endpoints and/or data analyses is acceptable to support regulatory approval. In addition to the SPA for Study 301, the FDA granted Fast Track designation to Chelsea's pivotal program in NOH. Fast Track designation is designed to facilitate the review of products that address serious or potentially life-threatening conditions for which there is an unmet medical need and provides the option to file a New Drug Application (NDA) on a rolling basis. This permits the FDA to review the filing as it is received, expediting the review process.

The novel design of this multi-national, placebo-controlled trial consisted of an initial open-label dose titration followed by a 7-day open-label washout period prior to a 7-day double-blind randomized, placebo-controlled treatment period. During the open-label dose titration period, all patients were titrated to an optimal therapeutic dose of Northera, up to 600 mg t.i.d., and were required to demonstrate both a blood pressure and symptomatic improvement to be eligible for the blinded study. Once a patient's individual optimal therapeutic dose was determined, each patient was taken off drug and washed out for a 7-day period. Patients were then randomized to either placebo (N=79) or Northera treatment (N=81) for one week. At the end of the one-week period, patients were evaluated for changes in symptomatic benefit as measured by the composite OHQ. The modified intent to treat population consisted of 160 patients (65 PD, 25 MSA, 54 PAF, 16 other) enrolled across a total of 65 U.S. and international sites
